comp is very slow and performance is not very good

My computer is running very slowly lately. Not sure why. It takes a very long time to load up programs and the internet is also running slow. Not what it used to be like. I am running on Windows XP Home Edition and using IE and Opera browser. Also, there are some programs/files in my Add/Remove Programs control panel that do not have a remove or uninstall option. These include: 1300, 1300_Help, 1300Tour, 1300Trb, AiO_Scan, AIOMinimal, AiOSoftware, and many others.Please help. I have posted a Hijack This log.

By default it will install to C:\Program Files\Trend Micro\HijackThis.

Accept the license agreement by clicking the "I Accept" button.

Click on the "Do a system scan and save a log file" button. It will scan and then ask you to save the log.

Click "Save log" to save the log file and then the log will open in Notepad.

Click on "Edit -> Select All" then click on "Edit -> Copy" to copy the entire contents of the log.

Come back here to this thread and paste the log in your next reply.

Do NOT have HijackThis fix anything yet! Most of what it finds will be harmless or even required.

Delete the older version once you have successfully downloaded and installed the latest version.*/*
